<em>Gymnopus dryophilus</em> at Shad Landing in Worcester Co., Maryland (5/21/2013). Per Lance Biechele: This mushroom is often considered a 'weed' species and more than 20 variants are cited under the old name, <em>Collybia dryophila</em>. To complicate matters more, in 1983, mating 43 collections of <em>C. dryophila</em> revealed four distinct taxa (Vilgalys & Miller). Such details only enforce the difficulties of mushroom identification by amateurs. (Photo ID: 5956 - Psn: 50)
